Dynapac CA 25, 25D, 25PD, 25R, 3208 Parts Catalog

Mike Callahan here. If you’re ordering parts for a Dynapac roller and guessing part numbers, you’re billing a second trip to the dealer. This catalog ends that. It’s the factory spare parts catalogue — not a reprint, not a scan from some third-party aggregator. 322 pages of exploded views, reference numbers, and the exact part designations Dynapac used when they built the machine. I’ve used these on CA 25 units with Caterpillar 3208 diesels and on 25D models with the Fairfield torque hub assembly. The difference between a correct part and a return is a page number.

322 Pages of Factory Parts Breakdown

Thumb through the table of contents and you see nine groups. Frame, Drum, Engine, Transmission, Hydraulic System, Electrical Equipment, Driver’s Platform, Decals, Equipment. Each group has subsections — for example, Group 2 breaks the drum into drive units with Staffa and Fairfield options, then the torque hub assembly. That’s important because the torque hub on a CA25D/PD uses different bearings than the CA 25. The catalog lists those differences in the same section. Page references for every subassembly.

Get the Right Part Numbers for Your Engine

Group 3 covers three engine families: Caterpillar D-3145, Caterpillar D-3208, and Deutz F6L 912. Each gets its own sub-section with fuel system, air cleaner, radiator, and hydraulic pump gearing breakdown. If you’re swapping a pump on a Funk gearing setup, the catalog shows the Renondin and Prometheus alternatives too. The part numbers for the hydraulic pump gearing are specific to the engine configuration — mixing them costs a flange. I’ve seen it.

Dynapac CA 25, 25D, 25PD, 25R, 3208 Parts Catalog: Source Authenticity

This is an original Dynapac publication, printed in Sweden. The cover lists the telephone and telex number for Dynapac Heavy Equipment AB. Aftermarket catalogs often clip the part number suffixes or merge compatible lists. Factory catalogs don’t. The part number for a vibration hydraulic motor seal on a Caterpillar-equipped unit isn’t the same as the Deutz version. The factory catalog keeps them separate. If you trust your time, trust the Dynapac CA 25 Parts Catalog from the source.

What Tools and Equipment Are Listed in Group 9?

Group 9 is short — just two pages on standard tools and equipment. But those pages list the special socket sizes, pullers, and adapter plates that Dynapac designed into the tool kit for the CA 25 series. Missing a tool? This is where you find the OEM part number. A buddy of mine spent a day sourcing a puller for the Fairfield torque hub when the part number was right there in Group 9. Dynapac CA 25 Spare Parts Catalogue saves that kind of wasted time.

Drum Assembly and Torque Hub Coverage

Group 2 covers the drum in detail — CA 25 and CA25D/PD variations. The torque hub (Fairfield) is broken down into its planetary gears, bearings, and seals. This is where you verify the hub part number before ordering a rebuild kit. The catalog also includes the vibrating link with shock absorber. If your CA 25R has vibration issues, the part numbers for the damping element are listed. Dynapac CA 25 Series Spare Parts Catalog – Section: Group 9 Equipment shows exactly which group you need.

Understand the Hydraulic System Schematics

Group 5 opens with a hydraulic diagram, then splits propulsion, drum drive, steering, and vibration circuits. The variable displacement pump section covers the charge pump and control valve. For the CA25D/PD, the drum drive hydraulic motor and manifold valve get separate exploded views. When you need to order a seal kit for the steering unit, the catalog gives you the correct reference number. No guesswork on O-ring cross-sections.

Torque is mentioned in the context of the Fairfield torque hub assembly — the part numbers for the hub itself, not the torque spec. The service manual has those numbers. This catalog gives you the hub assembly breakdown so you can order the right planetary gear or bearing. Dynapac built these machines with specific revisions; the catalog reflects those revisions.

For background on why OEM parts catalogs are critical in heavy equipment, see Automotive Industry Overview. The same principles of factory-sourced data apply here.

Does this catalog include torque specifications for the engine or drum?

No. This is a parts catalog, not a service manual. Torque specs are in the Dynapac service manual.

Can I order parts directly from this catalog?

Yes. Each part has a reference number and a picture. You hand that number to your dealer and avoid returns. The catalog groups parts by assembly — for example, the CA 25 drum group lists the drum shell, shock absorber, and drive unit separately. If your Fairfield torque hub needs a new bearing, you find the exact bearing part number under the torque hub subsection in Group 2. There is no cross-referencing; the catalog was written by the factory that built the machine. Every component from the engine hood latch to the hydraulic pump gearing appears in its group. I’ve used it to pull a part for a 3208 injector pump coupling — matched the page reference in Group 3. The 322 pages cover all variants: CA 25, 25D, 25PD, 25R. Even the decals in Group 8 have part numbers. If you maintain these rollers, this catalog belongs on your workbench next to the service manual.
